1go ew 'Lv/omit may concern lBe it known that I, SALVATORE Seoane- MmLo, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Automobile Vibrating Horns, of which the following is a specification..

This invention 'relates to an automobile horn or alarm signal :of the vibrating or percussig type; and one object of the same. is to'provide ahorn of this character embodying a simpliiied construction which is exceptionally cheap in the cost of manufacture, yet eective `in its operation to produce a strong alarm sound.

With this-and other objects and advantages in view the invention-.consists in the parts which will be more fully .described rand claimed.

ln they drawing: Figurel is a sectional elevation of a'vibrating orpercussing horn embodying the vfeatures ofv the invention. Fig. 2 is a transverse vertical section taken in the plane of the line 2 2, 1.

AThe numeral .5 designates a casing suit ably struck up in cup" shape as shown to form a `practical inclosure and 'having a 'front flange 6. A simple form ofvresonator '7 is also provided and formed with a securing ange 8 whichis attached to the flange 'by suitable rivets or other analogous fasjtenings 9; `Between the flanges' 6 and 8 re,

spectively of the casing land the resonator, a

*diaphragm 10 is held by the fastenings 9, and at.,.its center this diaphragm has a' pro I jection 1v1` extending rearwardly therefrom particularly the disk 111. The rear side 15 binding post 16 is and is preferably thezblunt point of a screw 12 which is supported in the diaphragm by awasher disk 13 secured on the front of the diaphragm .and a rear disk 14. The disks 13 and 14: may be of insulating material, and

of the casing 5 has upper and lower binding and to these '18 and 19-are respectively con nected and form part of a 'battery circuit which includes as usual a pushbutton or analogouscircuit closing means, The upper fully insulated from the rear side 15 of the casing 5, and the lower binding post 17 is in m'etalllic connection witlrjsaidrear side of the casing. At the 4center of the rear side 15 of ythe casing and in metallic connection--therewith is an ad l iusting screw 21 having itsV point-,1,22 pro- S-pecicatlon of Letters Iatent.

construction and' arrangement ,of the several hereinafter 1 raten-tea nee, ie, lere..

`je'cted into the case and serving as one con-v j tion of the diaphragm 10 and the iiange 6 of the casing 5. rlhe spring 23 has an electrol magnet 24 secured thereto,"a contact or impactingbutton or disk 25 being mounted on the spring 23 in line with the point of attachment theretoofthe electro-magnet, said impacting button or disk 25 being in line with the projection 11 and formed of metal. Secured to the lower end of the spring is an insulating connector 26having a spring arm .27 fixed to its rear end and extending upwardly and provided with a terminal armature 28, which in the present instance is in the form ofa metal plate bent over and secured to the upper end of the spring in `line with the pole 29 of the magnet 211. The armature 28 carries a. contact 30 which normally engages the contact 22 or the point of the screw 21. The one terminal of the windingof the electro-magnet is connected `by a wire 31 to the binding post 16 and the other or opposite terminal of said winding is connected by a wire 32 to the spring arm 27.

lt will be observed that the spring 23 carries the electro-magnet 24v, spring arm. 27 and armature 28 in suspended relation within` the casing 5, and'the several parts of this actuating mechanism can be simultaneously installed or placed. in operative position within the casing 4at a very small cost and without requiring any accurate adjustment, it being proposed to so primarily proportion and arrange the parts that a quickoperative assemblage may be obtainedby simply securing the spring 23 to the upper portion of the casing, as hereinbefore explained, when' the impacting button or disk 25 and armature 28 with the contact 30 will be in proper position relatively .to the projection 11 and the contact 22. When the circuit including the wires 18 and 19 is closed, the said circuit being from' -the binding post 16 lby wire 31 through the electro-magnet r241, over vwire 32 to the spring 27, from spring 27 by way of the contact 30 to the screw'21, and from the screw' 21 through the rear side or back 15 of the casing 5to the binding post 17 and out through the wirej'l). When the circuit is thus closed .the electro-magnet 24 becomes energized and attracts the armature 28, and

at the same time the impacting button or i.

disk 25 is drawn toward the projection 11 owing to the magnetism that is set up. As soon as the armature 28 is drawn toward the 4llijole of the electro-magnet the engagement etwen the contacts 22 and 30 is broken and a release is effected by reason of the broken circuit and the parts returned to their normal position as shown by Fig. 1,

and immediately the circuit is again made 'and an impact between the button or disk 25 manufacture and may be produced and placed upon the market at a duced price.

What is claimed is:V 1. In an automobile horn of the class specified, the combination of a casing,` a resonator'secured thereto, a diaphragm between the casing and resonator provided: with materially re a rear proj eetion at the center thereof, a mainsuspending and carr ing spring secured to the upper portionv o the casing within the latter and having an electro-magnet attached to the rear side thereof and an impacting Ydisk at the front side of the spring in line ywith the projection of the diaphragm, an insulating connector secured to and projecting from the free end of the said main spring, an upwardly extending spring arm secured 'to the insulating connector and spaced from the said main spring and providedwith an armature at its upper free end in operative adjacency to the pole of the magnet, the armaturealso carrying a contact projection,

a contact adjustably mounted in the rear of the casing and normally in engagement with the contact on the armature, and electrical connections forqathe electro-magnet and armature whereby when the circuit is closeda vibration of the main spring will be set up vby the action of the magnet and the s ecied p ragni held between the casing and resona- 4 phragm and comprising an elongated main I armature to effect a rapidv impact of the disk on the said latter spring with the projectiony on the diaphragm. j

l2. In an automobile horn of the class a casing, a resonator, a diator and provided with a rearwardly extend lng projection, a vibrating organization suspended within the basing in rearof the diaelectrical connections for the witnesses.
